UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Neisseria subflava Type 6 Secretion System competition with bacterial and fungal species
The aim of this study was to assess whether a Type VI Secretion System (T6SS) present in the commensal, non-pathogenic Neisseria subflava strain KU1003-01 plays a role in competition between these bacteria and other commensal and pathogenic Gram-negative

IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Anti-type VI tactics: bacterial defenses against type VI secretion system attacks
Survival of bacteria in dense and competitive microbial communities depends on their ability to access nutrients or outcompete neighboring cells. One of the key players in competition is the type VI secretion system (T6SS), a contractile nanomachine that injects a broad variety of effectors into competitors.

Type VI secretion systems (T6SS) are bacterial molecular machines translocating effector proteins into target cells. T6SS are widely present in Gram-negative bacteria where they predominantly act to kill neighboring bacteria.

The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.

Glucose promotes bacterial fitness while simultaneously repressing a major virulence effector ppTse6
Background Pseudomonas plecoglossicida (P. plecoglossicida) is an important aquatic pathogen whose virulence is closely associated with the type VI secretion system effector ppTse6.
